Epididymis leads to vas deferens that ascend to the abdomen and loops over the urinary bladder. Vas deferens receives a duct from the seminal vesicle and opens into the urethra as the ejaculatory duct. Each vas deferens is 40cm (about 1.31 ft) long and it enters the abdominal cavity through the inguinal canal. The duct passes through the prostate gland and opens into the urethra.
The main function of vas deferens is to transport mature sperms from epididymis to ejaculatory duct for ejaculation.
